NextMove BX

Motion Controller

2, 3, 4 Axis

Positional Moves

Absolute & Relative move types allow high speed

point to point motion on one or all axes.

Speed, Acceleration & Deceleration can be defined

for each move type.

Tr a p e z o i d a l p rofiled moves provide the fastest point

to point move but exert the maximum jerk and shock

on a system.

S - r a m p p rofiled moves provide a more smooth

velocity profile that prolongs the life of machine

m e c h a n i c s .

C o n t o u r i n g allows a stream of point to point moves

to be blended together into a continuous and smooth

motion for one or more axes.

Splining allows a stream of moves, defined in terms

of position, velocity and time, to be blended together

into a continuous and smooth motion. Used in

applications where path speed and continuous

velocity are important.

Interpolated Moves

Linear Interpolation a c ross two to four axes allows

position moves to be defined in terms of a linear

vectors. Absolute and relative vectored moves are

s u p p o r t e d .

C i rcular Interpolation a c ross any pairs of axes allows

a complete or partial arc to be defined. Absolute and

relative circular moves are supported.

C o n t o u r i n g allows a string of linear and circ u l a r

interpolated moves to be blended together into a

continuous complex path of motion.

E l e c t ronic Cam replaces the traditional mechanical

cam with a vector/servo motor and software

p rogrammable cam profile. NextMove BX supports

one cam profile for each of the four axis. Any axis may

be defined as a Master input to a cam and multiple

Master/cam relationships are supported. There is a

fifth encoder input for an external Master encoder.

E l e c t ronic Gearbox & Clutch enable two motor

shafts to be linked together in precise synchro n i z a t i o n

with a software programmable gear ratio. NextMove

BX allows any axis to be geared to any Master. Any

axis may be defined as the Master and multiple

Master/gear relationships are supported

Flying Shear allows operations to be performed at

regular intervals on a continuously moving web.

Acceleration, synchronization and re t u rn stroke are

linked by software to the movement of the pro d u c t .

NextMove BX is programmed in Baldor’s easy to use MINT language, or in “C”. Both the MINT programming

language and C function libraries support a wide range of motion and control functions outlined below and

described more fully the beginning of this section.
